FIELD

The present disclosure relates to an improved system and method for wallpanel trim installation.

BACKGROUND

Wall panel trim systems and methods for installing wall panels are arelatively economic way of cladding the surfaces of buildings. However,prior wall panel trim systems and methods often require significant timeand skill to install, as the trim pieces may need to be cut to finetolerances in order to avoid unsightly gaps and to avoid sharp edges.Prior wall panel systems may also experience problems with the buildingsettling over time, which may cause installed trim pieces to becomemisaligned or distressed, causing siding to buckle, or windows to crackunder pressure.

In addition, prior wall panel systems may experience problems withtrapped moisture, which may cause damage to the installed panels andunderlying wall surfaces with mold and other issues related to trappedmoisture, shortening their life. Prior wall systems may also requireoffsite assembly, or may consist of only a few types of trim pieces,limiting the ability to measure accurately, and place panels quickly andwithout compromised finished appearances, such as unsightly visiblegaps. Poor installation can also impact wind load and water performance.Prior wall systems may also require a long learning curve to understandthe installation process, often limiting installation to specialtylabor, causing high installation costs.

What is needed is an improved wall panel trim reveal system and methodfor cladding the exterior of buildings with exterior wall panels whichovercomes at least some of the drawbacks and limitations as describedabove.

SUMMARY

The present disclosure relates to a system and method for wall paneltrim installation.

In an aspect, there is disclosed a plurality of horizontal and verticaltrim profiles having a back plate adapted to receive a top cap within abracket. The bracket includes a mounting base and walls extending upfrom either side of the base. At least one flange formed on the outsideof the walls extends outwardly, and forms a shallow channel forreceiving an adhesive or a sealant. Inwardly extending protrusionsformed near the top of the walls are adapted to engage correspondingprotrusions formed on a top cap which is received within the bracketformed in the mounting base.

In use, an adhesive is applied within the shallow channel of thelaterally extending flange prior to a wall panel being placed intoposition for mounting. The adhesive is also applied inside the adaptedwalls under the inwardly extruding protrusions, and thereby removingchatter caused by wind and movement between the back plate andcorresponding top cap. A corresponding top cap with one or moreextending flanges is then hammered along its length into the mountingbase to secure the wall panel between the at least one flange with theshallow channel and a flange portion of the top cap.

In an embodiment, each top cap is adapted to be received within thebracket of the mounting only part way, with clearance between the bottomof the top cap and the bottom of the mounting base. This clearance isprovided in order for fasteners, such as brad nails and weather sealedscrews, to be used to install a mounting base on a wall. This space mayalso be used as a channel for wiring, for lighting and solar panels, forexample.

In an embodiment, the mounting base includes a center line or a screwset line which assists an installer to properly position the mountingbase on a grid line drawn prior to installation. One or more pre-drilledapertures along the length of the mounting base which allows uniformspacing for the brad nails and weather sealed screws when installing amounting base.

In another embodiment, the top cap includes at least one flange whichincludes a bent portion which is positioned generally parallel to onewall of the mounting base. This allows the top cap to be used at an edgeof the wall where a transition is needed for another type of wallcovering.

In another embodiment, the mounting base includes a lateral extension ofthe mounting base to at least one side in order to provide a widermounting base which engages a wall.

In another embodiment, a pair of mounting bases are coupled at aninterlocking pivot point adapted to permit the pair of mounting bases tobe rotated at least partially relative to each other. This rotationallows the pair of mounting bases to be used at an inside corner or anoutside corner which forms a range of angles, including a right angle at90 degrees, and a range of acute or obtuse angles on either side of 90degrees.

In another embodiment, an integral profile forms an inside corner whichmay receive the edges of two wall panels at a right angle.

In another embodiment, a two-piece inside corner allows for open accessto measure and place a panel. This two-piece inside corner is also usedto accommodate building movement and building compression betweenfloors.

In another embodiment, an outside corner profile includes mounting basesformed at right angles which each mount to a wall with fasteners. Acorresponding outside corner top cap includes extending protrusionsadapted to engage a corresponding locking channel formed on the outsidecorner profile.

In another embodiment, there is an outside corner mounting base and topcap with a float to allow for building movement and building compressionbetween floors.

In another embodiment, at least one shallow channel extending from awall of the mounting base forms a channel which is at least partiallyparallel to the wall. This permits the profile to be used at a corner,or at a transition point between the wall panels and another type ofwall covering.

In another embodiment, the trim piece back plates are color coded, suchthat correct installation of the pieces is simplified. By uniquely colorcoding each type of trim piece, incorrect installation of the pieces inthe wrong location can be avoided.

In another embodiment, the wall panel trim system provides continuousairflow behind the installed panels via airflow gaps provided betweenall installed pieces.

In another embodiment, the wall panel trim system provides a built inthermal break which minimizes any inward deflection or warping ofpanels.

In another embodiment, one or more of the plurality of horizontal andvertical trim profiles include leveling guides to assist in leveling andsquaring the profiles as they are installed.

In another aspect, one or more of the plurality of horizontal andvertical trim profiles are adapted to be installed with suitable gaps toallow for vertical compression of a wall, particularly between floors ofa building.

In an embodiment, the horizontal trim profiles include a horizontalcompression top cap with an extended lower flange which initially coversany gap with a lower panel, and also allows a vertical trim compressionpiece to be positioned atop the extended lower flange of the horizontalcompression top cap.

Advantageously, this avoids buckling and deformation of any installedtrim profiles due to settling of a building wall over time, and theintegrity of the installed wall panel is maintained.

Various tools may be used during the panel installation process. Forexample, referring back to FIGS. 1(xxxiv)-1(xxxvii), a hammer block maybe used for protecting trim pieces during installation, particularly topcap trim pieces which may be hammered into position. The hammer blockmay be laid on top of a trim piece so that it absorbs any impact from ahammer, rather than the trim piece. Referring back to FIGS.1(xxxviii)-1(xxxxiii), a panel clip may be used for temporarily holdingpanels in position during installation of the wall panels. As shown inFIGS. 1(xxxxiv) and 1(xxxxv), in use, the panel clip is inserted into achannel of a trim piece, and is turned until its irregular shaped baseengages the walls of the channel, thereby holding the panel Ptemporarily in position. Advantageously, this allows a single installerto install a panel, rather than requiring a second person to hold thepanel in position while other work is being done to secure the panel.
